Byzantium, Constantinople and Istanbul, these names are addressed to the same place which now we call it as Istanbul. According to the latest excavation during the building of the Marmaray Tunnel in 2008, the history of Istanbul has begun from 6700 BC, that’s where they found numerous the remains of sinking ships belong to the earliest human settlement of the metropolis. In 700 BC, when the Greek Colonists led by King Byzas arrived in the city, they nailed down there because of the strategic location along the Bosphorus Strait, and late King Byzas named the city as Byzantium.
